Abstract
(EN)
The objective of the present invention is to provide a cloth prepreg for a fiber reinforced resin molded article having a surface in which the texture of a woven fabric comprising reinforcing fiber bundles can be seen through, and with which a molded article having an improved appearance can be obtained when compression molded, and a method for manufacturing the same; and a fiber reinforced resin molded article having a surface in which the texture of a woven fabric comprising reinforcing fiber bundles can be seen through, and having improved industrial productivity and improved appearance, and a method for manufacturing the same. Provided are a cloth prepreg having a surface in which the texture of a woven fabric having reinforcing fiber bundles as the warp and weft can be seen through, and having a weft slackness ratio of 0.0 to 0.2%; and a method for manufacturing a fiber reinforced resin molded article enabling a compression molded article having a surface in which the texture of a woven fabric can be seen through to be obtained by compression molding the cloth prepreg or a prepreg stacked body including one or more of said cloth prepregs.
